Leners Patent No. 93,496, dated August 1o, 1869.

IMPROVEMENT IN Samana-MACHINE.

The Schedule referred to in these Letters Patent and making part of thesame.

To all lwhom. ttmay concern:

. Be it known that we, DANIEL B. Slnoxii'r and WIL- LIAM B'UsKIRmofWinchester, in thel county of Clark, and in the State of Missouri, haveinvent-cd new and useful Improvements in Shingle-Machines; and they dohereby declare that, the following is a full, clear, and exactdescription thereof', reference being had to the annexed drawings,making. part of this specifica-` a man can work in taking off hand eachshingleas.

it is cut, and removing it fmin the knife, to make way for itssuccessor.

In our improvement, the machine is self-clearing, and may .be run byhand, so' as to cut from fifteen hundred to two thousand shingles perhour.

In the drawing- A A are the sills, and

B B are the uprights of our machine.

O is a platform, on which the feeder or attendant stands, and

D is the bed, on which the `block froln which the shingles are cut,is'to rest as it is fed to the machine.

E is the driving-shaft, having at one Vo1 both sides of the machine afly-wheel, F, which may each be flu'- nished with a crank, when themachine is to be run by hand, or a'pulley, when it is to berun by otherthan hand-power.

In the centre of the shaft is a crank, l', to the pin of which isconnected one end of the pitman G, vthe other end being attached to theknife-sash, as will' be hereafter described.

'lo the uprights B are firmly attached the guides II H, each having agroove, in which'tlie sliding edges of the knife-sash work.

I I are the uprights or slides of the knife-sash, and to ,these hprightsis bolted the knife K, as seen i the drawing where. figjl shows a frontview,'and iig. 4, an enlarged rear elevation ofthe sash.

I l' are cross-ties, connecting the nprights or slides I l.`

It will be seen, on reference to figs. 3 and 5, that a v space`is'openbetween the edge of the knife andthe front face of the upper cross-tie1', through which the shingle will pass, after being separated from itsblock,

as indicated by the arrow.

lwouprights, a a, extend from one cross-tie I to the other, between theslides I, and two other nprights a a', near the centre of the sash,strengthen it, and

afford a bearing for the pin, to which the upper end of the pitman G isattached by a strap-joint. (See figs. 3, 4, 5, and 6.)

The slides I, cross-ties I', and uprghts a a', may be all .one casting.l

An upright spindle, b, extends from the centre of one cross-tie I to theother, and is made adjustable to or from the front of the machine, bybeing. allowed to move laterally'in the slots ff, through thecross-ties,

and in which it may be xed by tightening the nut at its uppeil end,while the set-screws c c will prevent it and the gauge-plate L frombeing forced back, as thc block is brought up against the plate.

By this arrangement is determined and fixed the thckness'of 'the shingleat the middle of its length.

'lfhe gangeplateL is hung upon the spindle b, so as to vibrate in such amanner that the plane of its face may be presented obliquely'to theshingle-block, toward'either side ofthe machine. Y I

The taper of the shingle, as shown in ig. 6, wherethe edge of the knifeis represented by the broken and` Adotted line, is determined by thedegree of oblique vibration allowed to the plate L, and this is fixed bythe temper-screws l d (l (l, which are tapped through the uprights a a.t

To the face of the gauge-plate are attached two springs c e, which maybe fixed in recesses in vthe plate,

so that when the block is held against thc plate, the

springs will be Hush with its surface.

These springs extend up above the top edge of the gauge-plate, andbehind the knife above its edge, pressing againstJ the back face of theknife, when not forced into their recesses in the plate, as seen in iig.5.

When a shingle is being out, it passes, as the knife descends, betweenits rear face and the spring. It is there held whileA the knife ascendsto make a new cut,

and as this is done, o n the descent of the knife, the

shingle that -was held' between the springs and the knife is pushed outand rearwards by the shingle that takes its place, and ,is held untilit, in its turn, gives place to another. n As the shingles fall, theyare conveyed bythe chute or incline M, to a point convenient forbundling.-

Having thus fully described our invention, What we claim therein as new,and desire to secure by Letters Patent, is

The gauge-plate L, in combination with the spindle b, slots fi,.set-screws c c, andv temper-screws d d d d, substantially as and forthe purposes set forth.

AIn testimony that we claim the above-described improvements inshingle-machines, we have hereunto signed our names, this 8th day ofJune, .1867.
